This lens hood does absolutely not fit on the barrel 18-55 mm or 50 mm on. I bought this product for anything, it is unusable. Among the many comments, or the majority of people received it unsuitable sunshade, there are some lucky few who have succeeded: they have necessarily received another visor as mine. The seller obviously sends two kinds of flowers, those that are consistent with the description and other containers which are like the one I received.
